I think you'd be fine to do this. You have a B3D license and it doesn't come with any restrictions, use it for whatever you want aside from re-selling B3D itself.
Of course there's the problem ... in a way it is re-selling B3D functionality so you might run into a problem with Mark on that one. It's not like you're really making anything with it. You'd be better off to just instruct people on how to do this for free, the issue being that they'd have to buy B3D and pay Mark who in turn pays Brett or whatever his name is.
Life's pretty easy, if you're actually doing some real work you should be in the clear, if you plan on making a lot of profit from something without doing any work you're unjustified. In this instance, you be the judge of how tough it is to make an audio handler with B3D and whether or not you're just copying FMod ... if you are then let them sell their product.
From what it sounds like, I think you should pass this off as free advice. In the end the people that did the real work (Mark and Brett) will profit accordingly. Afterall, B3D is meant to create full featured applications, not re-sellable wrappers to it's functionality.
